Portland fleet transmission repair: diagnostics, fluid & filter service, seal & gasket replacement & clutch adjustments.
Schedule an appointmentAt Trans Medic Transmissions, our fleet transmission repair service is engineered for businesses that depend on reliable, high-mileage performance. We start with a full electronic scan and road-load simulation to identify worn clutches, slipping bands, pressure leaks, or control-module faults.
Each vehicle then receives a tailored repair plan—seal and gasket replacement, solenoid servicing, clutch pack adjustments, or component rebuilds—so you get precise fixes without unnecessary downtime. Our goal is to restore optimal line pressure and shift quality across every truck in your operation, prolonging transmission life and reducing long-term costs.
